AA3 is out on the Unreal Engine 3 and so far it's been...a bugfest.
I was doing the training assault course and the roll animation locked up and my player looked more like a synchronised swimmer than a soldier in training.
And even after successfully completing a training session it doesn't mean you can move on to the next session. It looks like the server is having a wealth of issues. In addition, the bugs that were raised in the Beta version are still there. Somebody needs to give us 50 press ups.
Sounds like its a good thing I didn't preload. If its bug infested and I play it I probably wouldn't play it when they fixed some.
